Create a single-use benchmark workspace
Creates an empty workspace for one trial, owned by the caller, with one scoped key. The parent pays for its usage: the workspace budget (rcus) is held on the parent’s wallet and settled for actual consumption after retirement; runs use the parent’s connected provider accounts. It admits exactly one Session, created with mode ephemeral, and is retired at expiry or by the retire operation.

}Authorizations
Your Reason API key from Settings > API. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, knowledge:read, memory:read, memory:write, skills:read, skills:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, automations:read, automations:write, agent_auth:read. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:read reads sessions, including the assistant, reasoning and tool activity in their events. sessions:debug is privileged: only for organization owners/admins, it expands session events to the full diagnostic projection (diagnostic event kinds, status text and raw event metadata).
Path Parameters
Organization id or slug. Resolve it with GET /v3/self.
Body
application/json
Caller trial identifier. The same request replays the same workspace and key; a different request with this reference conflicts.
Required string length:
1 - 200Pattern:
^[A-Za-z0-9._:-]+$Lifetime before the workspace is retired automatically. Defaults to 240.
Required range:
5 <= x <= 720Workspace budget held on the parent's wallet and charged for actual use after retirement. Decimal string, defaults to 30, maximum 300; 0 runs only on the parent's connected provider accounts (BYOK).
Response
Replayed an identical request.
Pattern:
^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$Pattern:
